| 6/24/26 | The Tech Industry Forgot That Women Exist | Dr Anne-Marie Imafidon | Women in tech, AI bias, gender inequality, and the future of work Dr Anne-Marie Imafidon pulls no punches. Child prodigy, STEMettes founder, Countdown arithmetician, and government adviser on women in technology. She built STEMettes from £300 to £1.2 million. She watched the internet lose its mind over a Black woman doing maths on daytime TV. And she's spent 13 years trying to fix a tech industry that keeps building products that forget half the world exists. In this episode: why tolerating a brilliant jerk is a leadership failure. What leaders actually mean when they say they "can't find" female talent. Why crash test dummies based on women's bodies only arrived in 2025. And what a portfolio career looks like when you're genuinely living one. We also get into work, life, and legacy as a single equation - and why her definition of success has nothing to do with status. Dr Anne-Marie Imafidon - Head STEMette, DSIT Women in Tech Envoy, Chancellor of Glasgow Caledonian University, former Countdown arithmetician.

| 6/17/26 | What David Miliband & The Nudge Unit Taught Me About Leadership | Ravi Gurumurthy, Nesta CEO | Ravi Gurumurthy on Leading Nesta: Missions, Policy, Experimentation, and Intrinsic Motivation Welcome to What We Don't Know. The show about better leadership in a truly chaotic world. Today, Hayaatun is joined by Jimmy McLoughlin OBE, host of @jimmysjobs, to chat with Ravi Gurumurthy, CEO of Nesta, about leading mission-driven innovation in an uncertain world. Ravi explains Nesta’s three “moonshot” missions - halving obesity, achieving net zero homes, and closing the school-readiness gap for children on free school meals, and shaping policy from practical learning. Ravi also reflects on his background in Burnley, early rebellious leadership, experiences of racism, and a rapid rise in the civil service, including work on Every Child Matters, the Children Act 2004, and the Climate Change Act. We also cover policymaking’s short-termism, better use of data and trials, how AI and synthetic data could help, learning from failure through “crash testing,” the importance of dosage and numbers, and why leaders should focus on intrinsic motivation over incentives.
